摘要： Disclosed is a method of preventing optical recording media from being fractured and apparatus thereof, which enable to prevent an optical disc of an optical disc drive from being fractured due to a crack. The method and apparatus comprise: detecting a first tracking error signal outputted from a data recording/reproducing apparatus when the optical recording media are rotated at a first speed; detecting a second tracking error signal outputted from the data recording/reproducing apparatus when the optical recording media are rotated at a second speed; determining whether or not the crack on the optical disc exists on the basis of the first tracking error signal and the second tracking error signal; and stopping an operation of the data recording/reproducing apparatus when the optical recording media have the crack.

摘要： The present invention discloses an optical disk formed according to double injection molding of forming an area of the optical disk on which a recording film is formed, namely, an outer circumferential area by using polycarbonate that is an amorphous polymer, and forming an area of the optical disk on which the recording film is not formed, namely, an inner circumferential area by using a semi-crystalline polymer having a similar elastic modulus to that of polycarbonate and having durability to a static fatigue, especially polyamide. Therefore, the optical disk is efficiently prevented from being damaged by restricting growth of cracks near its hole, obtaining excellent optical characteristics as an information recording medium.

摘要： A toy having a detachable central processing unit is disclosed and includes a central processing unit having a growth algorithm for learning purposes, a driving unit for exhibiting learned actions and functions, and a link unit for linking the central processing unit and the driving unit. When the central processing unit is detached from the driving unit, the toy can learn via a cyber character or can be utilized as a Personal Digital Assistant (PDA), mobile phone, or a personal computer. When the driving unit is linked to the central processing unit, the toy's learning abilities are improved.

摘要： An optical disc drive include a turntable for mounting an optical disc, a driving unit rotating the turntable, and an optical disc heating member for heating a center portion of the optical disc. In the optical disc drive, an inner circumference temperature of the optical disc is maintained to be higher than a peripheral temperature of the optical disc by at least 50° C. According to this, a growth of a crack generated at a periphery of a hole of the optical disc is restrained thereby to effectively prevent a damage of the optical disc.

摘要： A tray of an optical disk player including a disk mounting portion on which an optical disk is stably mounted; a front wall formed on the front to surround the disk mounting portion; a rear wall formed on the rear of the tray to surround the disk mounting portion, the front wall is formed to have a distance from the center of a spindle to the front wall not less than a value obtained by adding 2.75 mm to a radius of a large-sized disk and not greater than a distance from the center of the spindle to a tray front end. In the tray, by increasing a flutter occurrence speed, although the optical disk player has a high recording/reproducing speed, occurrence of flutter can be prevented, and accordingly it is possible to reduce error in disk reproducing/recording and prevent noise occurrence and wrong operation.
